Default Proven principle: "Rockets not carrying fuel" and the space tower.

If this is feasible we might use it also to limit the destructiveness
of hurricanes. A single hurricane can cause thousands of deaths and
billions of dollars in damage. Interestingly it is known that a
reduction of only 5 degrees Fahrenheit in the ocean surface
temperature can cause a hurricane to dissipate. Because of that I
suggested putting cooling chemicals or ice in the path of a hurricane
to reduce its strength:

The problem would be getting the required massive amounts to the area
in time. The raised pipeline might provide a means to accomplish this.
There are pumps that can put out hundreds of cubic meters or hundreds
of metric tons of water a second:

If you pumped the water mixed with the right freezing point lowering
salt, the water could be kept liquid at temperatures of dozens of
degrees below freezing and you might only need in the range of tens of
thousands of metric tons to accomplish the temperature drop, which
could be pumped with these largest pumps in a matter of minutes.


Cooling the water to be pumped, as well generating the energy
required to pump it, would probably generate its own storm
system. Where are you going to dump all that heat?
